The hydronium ion concentration in coffee is 1 x 10^-5 M. What is the pH of coffee?

pH = -log(H^+)
pH= -log(H+)=5 Yep, it is acid, it rots your teeth
The only difference is that lemon juice rots teeth faster since it is about 1000 times stronger.
True because I did learn that the lower the pH the more acidic it is.
